What is wrong here ? only the test case 3 failed and i dont know why ?

Question

#include <iostream>
using namespace std;

int main() {

int s[5];

for (int i = 0; i < 5; ++i) {
cin >> s[i];
}

int a=s[0];
int b=s[1];
int c=s[2];
int d=s[3];
int e=s[4];

if ((a<b)&&(a<c)&&(a<d)&&(a<e)){
float w=a;
float p=(w/100)*50;
float y=50-p;
cout<<y<<endl;
}
if ((d<b)&&(d<c)&&(d<a)&&(d<e)){
float w=d;
float p=(w/100)*50;
float y=50-p;
cout<<y<<endl;
}
if ((e<b)&&(e<c)&&(e<d)&&(e<a)){
float w=e;
float p=(w/100)*50;
float y=50-p;
cout<<y<<endl;
}
if ((b<a)&&(b<c)&&(b<d)&&(b<e)){
float w=b;
float p=(w/100)*50;
float y=50-p;
cout<<y<<endl;
}
if ((c<b)&&(c<a)&&(c<d)&&(c<e)){
float w=c;
float p=(w/100)*50;
float y=50-p;
cout<<y<<endl;
}

return 0;
}

Answer 1

Your program will not print anything when ages of all people will be equal, probably you need to find minimum value.
Replacing all < by <= may help to find minimum value, if you can provide problem link it will be easy for community to help you.

It can simplified, just take w as a large value (greater than constraints on a, b...e) and iterate though all values and do w=min(w, s[i]).

Answer 2

You need to create a program that takes the ages of all 5 people as input and outputs the total price of the tickets.

Sample Input:
55
28
15
38
63

Sample Output:
42.5

The youngest age is 15, so the group gets a 15% discount from the total price, which is $50 - 15% = $42.5 this is qn

Answer 3

Use if-else instead of only if.
Why you are adding redundant code..? You can only find small one in if-else, and after last find y out-of is-else. That removes repeatations.. Simplifies..
